VAPOR LAMP AND BURNER.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed August 16, 1907, Serial No. 388,907. Renewed November 21, 1908. Serial No. 463,890.

To all whom it may concern:

Be it known that I, BERNARD CnAnoNNn, engineer, residmg at 11 Marles road, West Kensington, London, N, England, have invented certain new and useful Improvements in Vapor Lamps and Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in or connected with vapor lamps and burners, the object being to provide a simple device whereby a cleaner flame is produced than hitherto, the present invention being particularly applicable for use in connection with burners for heating incandescent manties in lighting lamps.

In order that this invention may be fully understood, it will now be described with reference to the accompanying drawings in which Figure 1 illustrates in side elevation a lamp constructed according to this invention, with part broken away for clearness, Fig. 2 is a plan thereof with the top dome of the lamp removed, and Fig. 3 is a longitudinal partial sectional side elevation of the regulating valve hereinafter described.

In carrying this invention into practical effect and as shown in the drawings, the kerosene supply pipe a is arranged horizontally above the burner b which is arranged in a well I) designed to contain spirit or the like as hereinafter described. This supply pipe communicates with a second horizontal pipe (1/ by means of a right angled extension (1 furnished with a screw cap a for cleaning purposes. The pipe a is formed with a pin hole outlet 0 opening into a comparatively large chamber d which is open to the atmosphere at each extremity (Z, within the dome of the lamp 6, and this air chamber (Z, at a point opposite the aforesaid pin hole outlet 0, communicates with the main supply pipe f to the burner b.

In practice, the well I) is filled with spirit or the like which is ignited and heats the kerosene supply pipes and vaporizing pipes a and a, the pipe 0/ being fluted as at a to facilitate this; this heating has the effect of vaporizing the kerosene contained therein,

the said vapor passing up through the pin hole outlet 0 in the pipe at, across the air chamber d and around the burner supply pipe f taking with it a sufficient quantity of air from the said chamber (Z to provide an atmospheric flame which will not blacken the incandescent mantle, and further vaporization of the kerosene is effected by the heat from the burner w ien once lighted.

In order to prevent the pin hole outlet 0 becoming choked, and to regulate the supply of vapor, the needle valve illustrated in Fig. 3 is employed, according to which a needle 9 is arranged in the pipe at, being carried by a rod g, near the extremity of which it is clamped between two set screws 9 The rod gterminates in a sleeve 9' formed with a cam-groove g engaging a pin h carried by a hollow plug it screwing into the pipe a and through this plug h, and asbestos or other packing contained therein, the needle g passes. It will thus be seen that upon turning the rod g, which may be provided with a suitable handle or cross bar at its extremity for this purpose, the ca1n-groove g will cause the rod and needle 9 to travel backward or forward according to the direction in which the former is turned, thereby drawing the needle point farther from or pressing it farther into the pin hole outlet 0 according to whether a greater or lesser supply of vapor is required and this needle is also capable of being employed to clear the pin hole outlet 0 of any corrosive substance, while as a further safeguard in this respect, it is pre ferred to arrange a roll of wire gauze i within the pipe at, through which the needle a passes. Surplus kerosene is also prevented from passing to the needle point and pin hole 0 by means of a perforated sleeve j passing around the needle 9 and between this sleeve and the pipe 0/, asbestos fiber or other suitable material is closely packed, this packing also preventing overheating of the needle oint.

What I c aim is In a vapor lamp, the combination, with an air supply chamber, of a vapor supply pipe having its upper end secured to the said chamber and provided at its lower end with a burner, an upper vaporizing pipe also secured to the said air chamber and provided with a regulating valve, a branch lntestimony whereofI-afiix my signature, vaporizing pipe dlependigg .fr'efn the saig in presence of two Witnesses.
